Red Sea Reef Foundation A Calcium+ (Ca,Sr,Ba) 5 litre/5000ml
Red Sea’s Reef Foundation program is designed to provide optimum conditions for a thriving coral reef starting with the fundamental building block elements or foundation elements needed for healthy coral growth and development.
Foundation A Calcium+ is a balanced blend of calcium, strontium, and barium needed for the development of the coral skeleton, in balanced proportions in one complex blend as part of the Red Sea Reef Foundation Program.
As a rule 1ml of Red Sea’s Calcium+ supplement will raise the level of calcium by 2ppm in 100 litres of water, however, it’s advised to test your water first with Red Sea’s Reef Foundation test kit to find you’re stating dose and then work from the table Red Sea provided with all the Foundation Element Supplements.
